How to solve the threat of wireless network security (II.)

Security threats under the facilitation of networking

Since low grade wireless LANs have some of these security drawbacks, if they suddenly attack or are exploited by an illegal attacker, they can pose a security threat:

1, causing privacy information leakage

In some cases, many wireless LAN users in order to facilitate the work, often inadvertently will be the unit's important privacy information or core work information, or even some of the confidential category of information through mobile devices to hang up the wireless LAN network, so invisible in the vulnerable to the risk of important private information leakage, Serious time can cause huge economic losses to the unit or individual.

2. Reduce intranet security capability

Unit wireless local Area network Sometimes there will be some home wireless LAN or other units of wireless LAN, these wireless LANs are often used for mobile office or share access to Internet network, these wireless network users are not enough security awareness, And they do not have a high demand for wireless networks, and do not need to do some security for wireless internet access. In this case, any laptop that has a wireless network card installed in the unit may automatically connect to other units of the wireless LAN, so it is easy to occur this unit of wireless LAN and other units of the wireless LAN directly interconnected phenomenon, Even may appear the unit wireless local area network directly with the Internet interconnection phenomenon, these phenomena obviously can reduce the unit intranet security guard ability, easy to cause the unit to have the serious security consequence.

3. Endanger Information System security

Considering the low cost of lower grade wireless LAN network, do not need to carry out complex wiring, management and maintenance is also very convenient, if the security awareness is not in place, then some smaller units are likely for technology, cost and other factors, to choose some inexpensive, poor quality wireless network equipment for networking upgrades, information points of the extension, Networks built from these networks will naturally be exposed to the outside world, wireless network access can not be effective physical isolation, so that the unit's information systems security will be compromised at any time.

Resolving wireless network security threats

Although low grade wireless LAN is easy to bring us all kinds of unexpected security threats, will give the unit of the information system caused no small security risks, but for those who are not very high security requirements of small units, still can choose the low grade wireless LAN, after all, this type of networking cost is very low, More importantly, through the development of effective measures can completely reduce the security threat of low grade wireless LAN to a minimum, so that the small unit users can enjoy the networking facilities.

1, to check to be safe

In order to understand the security status of the Unit wireless network at any time, we should regularly check the internal intranet, extranet usage and the working status of the core network equipment, and do a detailed inspection record. At the same time, we should also increase the intensity of the wireless network in the vicinity of the wireless LAN work environment for dynamic monitoring, a certain time also need to the unit of the Network system security assessment and audit; In addition, for organizations involved in the organization of core privacy information and the implementation of important network applications of the workplace, Electromagnetic shielding should be adopted in time to prevent illegal network intrusion or attack.

2, to the publicity to be safe

Because the low grade wireless LAN is very easy to affect the use of internal network security, for this unit responsible must be prepared rich network security information, in the unit, under the regular development of wireless internet Security knowledge publicity, training, in order to enhance the safety of every wireless Internet users awareness, At the same time, it is necessary to carry out special rectification work of network security, to ensure that all staff can attach great importance to the work of wireless network security.

3, to the management to be safe

As the saying goes, "no rules, radius", in order to ensure the use of wireless LAN Security, we also have to make reasonable provisions for the use of wireless network equipment, wireless internet users to reasonably manage, standardize the work mode of wireless network equipment and security settings, clear access to the user's scope of use and access rights; , prohibit the preservation of important unit information notebook computer connected to the wireless local area network, prohibit random in the wireless local area network share access, prohibit the mobile devices to arbitrarily hang wireless LAN, for storage, processing the core information of the workplace must be shielded protection and so on.

I believe in a sober understanding of the existence of low-level wireless LAN Security threats, we only take effective security measures to prevent, or can enjoy the convenience of wireless network, so that low grade wireless LAN can also be very good for us to provide "services."
